You ought to be able to drive in almost any direction and eventually come upon a farmer. Don't carry the rifle with you, be respectful, and sincerely ask him if there are any outdoor places that he would know of that could oblige you. Be ready to offer money, possibly to him or whatever place he names. Most of northern rural Kansas hunts some thing. Whether pheasant, waterfowl or white tails. Most just want to make sure you're not going to A; shoot them, B; shoot yourself, C; scare game or put holes in something you otherwise ought not...
I suppose this means I'm talking to a Jayhawker, eh?
